Quick answer: Use a sturdy cube shelf unit as the base, add sanded, sealed pallet-board perches at staggered heights above it, and line two cubbies as hideaways. Choose HT-stamped pallets only, finish with a water-based sealer, and strap the unit to the wall. The result reads as a bookcase with a wood top, not a cat tree.
In an apartment, a carpeted cat tree is often the biggest, least attractive piece in the room. Cube shelving units are everywhere, and they're strong, square and easy to cover. Add reclaimed pallet wood and you get warm, textured perches that sit on top like a designer sideboard with a bit of extra height.
This hack keeps most of the structure inside the shelf, so the tower stays compact. The pallet wood carries the look and the climbing. For the original IKEA cat tree idea, see our IKEA hack cat tree, and for the full range of tower plans, the DIY cat tree hub.
Choosing the base unit
Look for a cube unit with solid sides and a full back panel, which resists racking when a cat jumps on it. A 2 by 4 cube unit laid on its side makes a long low base about 30 inches high; stood upright it's around 57 inches tall but narrow, and needs a wall strap. A 2 by 2 cube unit is a good starting block for very small spaces. Check the manufacturer's maximum load per shelf and keep heavy items low.
| Layout | Height | Footprint | Best for |
|---|---|---|---|
| 2x4 lying flat, perches above | About 30 in plus perches | Long and shallow | Under-window spots |
| 2x2 with tall perch post | About 30 in plus 24 in post | Small square | Studio apartments |
| 2x4 upright, side perches | About 57 in | Narrow | Corners, must be anchored |
Sourcing pallets that are safe indoors
Use only pallets stamped HT, meaning heat treated. Pass on any stamped MB, which means fumigated with methyl bromide, and any with stains, oily patches or a smell. The IPPC international standards explain the marking. Pallets from dry goods suppliers tend to be cleaner than those from chemical or food warehouses. Break them down with a pry bar and a reciprocating saw through the nails rather than splitting boards, and pull every nail stub with pliers.
Sanding and sealing for a furniture finish
Sand with 80 grit to remove grime and splinters, then 120 and 180 for a smooth surface that won't snag fur. Round every edge slightly. Seal with a water-based polyurethane or hardwax oil labelled low-VOC, and let it cure fully in a ventilated room before the cat uses it. Fresh finishes release vapours, and an apartment has less air to dilute them; EPA on VOCs and indoor air explains why airing matters. Our materials and finishes guide compares options.
Planning the look before cutting
Sketch the unit on paper with the pallet perches drawn to scale. Decide whether the wood will run front to back or side to side; boards running the long way across a perch look more like a tabletop and less like a crate. Lay out your de-nailed boards and sort them by colour and grain, putting the most attractive faces on the perches you'll see from the sofa. Rougher boards with nail holes can go on the hidden cubby backs. Mixing a pale shelf unit with mid-tone pallet wood gives a Scandinavian look; a black or walnut-effect unit with darker oiled pallet boards reads as more mid-century. Mid-century modern cat furniture ideas has more on that style.
Building the perches
Edge-glue three or four pallet boards into a panel about 16 by 20 inches. Screw two cleats underneath across the grain to stop cupping. For perches that sit on top of the shelf, screw through the cleats into the shelf top from below if possible, or use corner brackets. For a higher perch, mount a 4x4 or doubled stringer post at the back of the shelf top and fix the perch to it with a heavy angle bracket.
Stagger heights by about 12 to 14 inches so the cat steps rather than leaps. A cat jumping from 57 inches straight to the floor every day is hard on joints over the years.
Tools and parts list
- Cube shelf unit, assembled with all cam locks fully tightened.
- Two to three HT pallets, broken down and de-nailed.
- Wood glue, 1.25- and 2.5-inch screws, two heavy angle brackets.
- Random orbital sander with 80, 120 and 180 grit discs.
- Water-based sealer, a brush or cloth, and gloves.
- Furniture anchor kit with a stud finder.
- Natural sisal rope and a fabric sisal panel.
Before you start, check the shelf unit's assembly instructions. Some units need extra screws at the back panel to resist racking when used on their side.
Cubbies as hideaways
Leave two cubes open and line them with a cushion or a folded fleece. Cats like a hiding spot below the lookout. Close the back of one cube with a pallet board panel to make it darker and cosier. Use fabric bins in the remaining cubes for your own storage, so the unit still works as furniture. Cat furniture that doesn't look like cat furniture has more ways to blend function and style.
Adding sisal without making it look like a cat tree
Wrap the high perch post in natural sisal rope, which looks like a design detail next to pallet wood. On the shelf side, glue a sisal fabric panel into the back of one cube to create a vertical scratching face. Avoid carpet on the perches; leave the sealed wood bare, or add a removable fleece pad on the top perch.
Introducing your cat to the tower
Put the tower in place, then drop a few treats on the lowest perch and leave it be. Play with a wand toy so the cat climbs while chasing it, starting low and moving up over a few sessions. Move a familiar blanket into one of the cubbies so it smells like home. Most cats explore within a day or two. If yours doesn't, check for wobble or a slippery perch surface, both of which put cats off quickly.
Cleaning and upkeep
Vacuum perches weekly and wipe the sealed wood with a damp cloth. Wash cubby pads monthly. Every few months, check the screws in the perch cleats and brackets, tighten anything that has loosened, and look for raised grain or splinters on high-traffic edges. A light sand and a fresh coat of sealer every year or two keeps the wood looking like furniture. Replace the sisal wrap on the post when it frays through. Our stud-safe tower build has more detail on fixing posts so they stay rigid.
Budget and time
The shelf unit is usually the main cash cost, and second-hand cube units are common on local marketplaces, often for much less than new. Pallets are frequently free from local businesses if you ask. Budget for sisal rope, screws, brackets, sealer, sanding discs and an anchor kit. Allow a full day for pallet breakdown and sanding, an evening for assembly, and at least a couple of days for the finish to cure before the cat moves in. Kept clean and tightened, a build like this can serve for years, and the shelf unit goes back to being a bookcase if you ever retire the perches.
Anchoring in a rental
An upright unit with a cat on top can tip. Strap it to a wall stud with a furniture anchor kit. Most leases accept small screw holes, which are filled with spackle when you move; check yours and ask your landlord if unsure. The CPSC Anchor It campaign shows how anchors work. If anchoring isn't possible at all, use the lying-flat layout and keep perches low and centred. Our stability test helps you check for wobble before the cat moves in.
Fitting it into a small apartment
Place it near a window so the top perch gives a view; this alone makes it the cat's favourite spot. Keep it away from the kitchen counter, or the tower becomes a launch pad. If floor space is tight, see the under-2-square-feet tower plan and our guide to cat furniture for small spaces.
IKEA hack pallet cat tower: FAQs
What IKEA unit works best?
A cube shelf unit with solid sides and a full back panel, in a 2x2 or 2x4 layout, makes the strongest base because the back panel stops the frame racking. Stand it upright for height or lay a 2x4 on its side for a low, wide tower. Second-hand units are often cheap locally; check the joints are tight and the panels are not swollen.
Are pallets safe for cats?
Pallets stamped HT, for heat treated, are a reasonable choice once they are clean, de-nailed, sanded and sealed. Avoid MB-stamped pallets, which were fumigated with methyl bromide, and any boards with stains, oil or a chemical smell. Local businesses often give pallets away, so you can afford to be choosy and reject anything that looks doubtful.
How do I stop the tower tipping?
Strap an upright unit to a wall stud with a furniture anchor kit; most leases accept small screw holes that you fill with spackle when you move out, but check yours. If anchoring is not allowed, lay the cube unit on its side and keep perches low and centred over the base. Push the finished tower from every side before your cat climbs it.
What finish should I use?
Use a water-based, low-VOC sealer such as clear water-based polyurethane, brushed on in thin coats and left to cure fully. Allow at least a couple of days with a window open before the cat moves in, and longer if you can still smell it. Avoid oil-based stains and exterior decking products, which can stay tacky and keep giving off fumes indoors.
Can I put carpet on the perches?
You can, but carpet makes the tower look like a pet product and holds onto fur and odour. Bare sealed wood topped with a removable fleece or felt pad keeps the furniture look and the pad goes straight in the washing machine. If your cat wants more grip, wrap one post or the inside of a cubby in sisal rather than carpeting every perch.
How long does an apartment pallet tower take to build?
Plan for a weekend plus curing time. Breaking down and sanding pallets takes most of a day, assembly and sealing take an evening, and the finish needs at least a couple more days to cure and air before your cat uses the tower. In an apartment, sand outdoors or on a balcony so the dust stays out of your living space.
Will pallet wood smell inside an apartment?
Clean HT pallets that are sanded and sealed should not leave a noticeable smell once the finish has cured. A lingering sour, oily or chemical odour usually points to one contaminated board, so remove and replace it rather than adding more sealer on top. Air the tower near an open window for a few days and keep it away from heaters while it cures.
